Open Source Service Companies

The Jump Box web site is inspiring as I see one more company capitalizing on the services industry that feeds off of open source software. I suppose that if you do not have the time or experience then you can rely on these services. Seasoned IT geeks like myself grew up with Linux and can appreciate the logic behind saving time when using any product.
What I want to point out is that there is paid support for any open source solution that we want to consider. An IT department does not want to place their business partners in a situation where any of the supplied solutions are not supported by outside vendors. IT departments must always want to allow their business partners an alternative to acquiring support for an installed solution. Ideally the on site staff can support most applications, but when times get rough you gotta have a second opinion and paid support must be available.
